Well, the Chinese seem to be godlike at controlling the map, but pretty shit at team fights compared to EU. At least if these are the games you want to use to make sweeping judgements about the quality of each region.

As far as the Koreans goes, Ozone didn't even make it out of group B, where two European teams made it out instead. Najin Sword then had to take Gambit to three games in the knockout rounds, and Fnatic absolutely dominates Gambit. So where exactly do you get the idea that Fnatic is any worse than SKT1 and NBS?

Where did I say that fnatic are worst than skt1 or nbs? Why are you putting words in my mouth? (It's very safe to say that sktt1, a team in the finals are better than fnatic though, especially in a bo3/bo5) Also that logic is shitty, things don't really work like that in the real world. Basically from eu/na there are two standout teams, fnatic and c9 who can play with everyone else. This is compared to all the ready teams from korea/china. So clearly there is a difference. Also, royal seemed to be just behind fnatic in teamfights and omg seemed superior in that aspect. I don't think any region has the best teamfighting, it's a difference in styles. I'm not talking about specific teams, you're not adding anything relevant. Again, second point.

How can you compare C9 to Fnatic in this regard?

Fnatic went 15 - 13 through the European Summer Split, while C9 went 25 - 3 in NA. C9 is a dominant force in North America, while there are at least 6 other teams in Europe on the same level as Fnatic.

How is it safe to say? SKT1 have fought a single Bo3 where they dominated a much worse team (Gamana Bears). At the same time Fnatic had to take down the most dominant NA team out there. SKTT1 then had to take NBS to five games in the Semi Finals, and NBS is a team that had huge issues getting past Gambit, a run-of-the-mill European LCS team this season.

Then you talk about the depth of the Asian scene, yet Ozone didn't even make it out of a group with two European teams and one from North America. This is in spite of Ozone being the 2nd best Korean team overall this season.

There is absolutely nothing to indicate that the Korean scene has any more depth than the European one. Quite the contrary, if you just bother looking at each region's preliminaries. The European scene was much more even than the Korean one was. The top 3 Korean teams were miles ahead of the rest.
